CABLE-TAKE-UP GRIP.

Application filed December 16, 1918.

To all whom it may concern:

scription of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same.

This invention relates to pulling devices,

such as stump-pullers and the like, and the purpose of the invention is to provide a simple and quickly operating take-up for the slack in cables, whereby longer for shorter hitches may be made without the necessity of reeling and unreeling the cable by turning the winch.

In the operation of pullingstumps, for example, it is necessary to shift from stump to stump, the distances of which from the winch will vary indefinitely. To unwind the cable to connect with a stump, or reel it up at the winch, to connect with a nearer one requires considerabletime and labor.

The take-up herein described admits of the use of a long cable for attaching to an object at any distance within its length, and in a fraction of the time required to operate the winch.

In the accompanying drawing, forming a part of this specification, Fig. 1 is a side view in perspective, showing the improved take-up as in use. Fig. 2 is a top view of the same detached. Fig. 3 is a bottom view of the same. Fig. 4 is a section of the same in the line H of Fig. 2.

In the drawing, the numeral 1 denotes the pulling winch having a cable drum 2 and power sweep 3. The winch is connected to some stable anchorage, as a stump 4, by a cable 5. On the drum is wound the pulling cable 6, which may be as long as desired. The pull of this cable is applied to the object to be pulled, a stump 7 for example, by an auxiliary cable 8, through the medium of the take-up which will now be described.

To the cable 8 is secured a strong casting, preferably of steel by its cable-end socket 9, in which the cable is leaded in a familiar way. The casting has a fiat top 10, slotted at 11, and is provided with an opening at 12. At the opposite end is an upstanding jaw 10, whose inner face is Specification of Letters Patent.

curved as shown. Lateral to this jaw is a hook 13 to receive thecable 6 in direct alignment with the cable 8, as seen from above, and after a turn thereof has been made about the gripping disk, 'to be described presently. serve to support the casting on the ground, and give space for the parts of the disk that connect with the casting. At one side is formed a handle 15 by which the takeup is carried.

On the flat top of the casting is mounted v a circular disk 16, provided with a circumferential groove 17 to receive the cable 6, a gap in the upper flange of the disk being made at 18to permit the dead-end portion of the cable to overlie the part that passes through the hook and on to the winch, as plainly-shown in Fig. 2. Atthe side of the disk which adjoins the jaw a depending lug 19 passes through the slot 11, and is provided with a retaining cotterpin 20. At the opposite side of the disk is a strong hook 21. which enters, the opening 12, and holds the flat lower face of the disk in contact with the topofthe casting, while.

allowing for a limited movement of the disk on said casting.

The operation of the device will be readily seen. When the cable 6 is slack its own elasticity forces the disk to open position with respect to the jaw of the casting, which may be designated as the fixed member. The operator may then easily detach the cable, and connect the cable 8 with another stump. Whether nearer or farther away, he has only to throw a loop of the cable 6 around the disk, and hold the loose end of the cable lightly while the winch takes up the slack. In so doing the disk is drawn bodily toward the jaw, a segment of the cable being gripped between them, the grip of the parts increasing as the strain increases.

The construction of the take-up is such that the cables 6 and 8 are brought to exact alignment under stress, the take-up tipping a little when such stress is applied. Any tendency of the take-up to twist is prevented by the guide-hook over the pulling cable. It is to be noted that the movement of the grooved disk is directly radial, insuring an equal distribution of pressure over the whole segment of cable gripped between it and the correspondingly curved face of the opposing jaw. This segment,

Depending flanges 1a member p rmanently attached to ample,

as will be seen, is a part of the dead end of the cable, and between it andthe active,

pulling part of the cable is a nearly complete turn of cable fitting snugly in a groove, the friction of which corresponds to: the friction of coils of rope snubbed around a post, and greatly relieves what would otherwise be ye'ry great'longitudi-' nal strain of the cable at the place gripped. This 7 relieves the cables of any excessive squeezing or "abrading' action under the m great strains to which it is sub]ec'ted."
